Shallow M6.4 earthquake hits southeast of Easter Island

A shallow M6.4 earthquake was registered at 07:49 UTC on October 29, 2026, southeast of Easter Island. The earthquake struck at a depth of 10.0 km (6.2 miles), with coordinates placing the epicenter at 36.4°S, 98.0°W.

The location of the earthquake is in a remote section of the southeastern Pacific Ocean, distant from significant population centers. Easter Island is the nearest inhabited landmass, situated considerably northwest of the epicenter.

Given the offshore setting in the southeastern Pacific, critical infrastructure in the immediate vicinity is minimal. The primary risk would be to maritime activity due to the remote, open-ocean location.

There is no tsunami threat associated with this earthquake, based on its location and available data.

USGS issued a green alert for this event, indicating a low likelihood of casualties or damage. The maximum estimated intensity is 0, and the significance index is 630 (on a scale that runs through 1 000), based on magnitude, felt reports, and estimated impact.

This region of the southeastern Pacific Ocean is situated near the boundary of the Nazca and Pacific tectonic plates, an area known for significant seismic activity caused by plate interactions.
